PUMP.

Application filed December 23. 1921.

To all wlwm it may concern:

Be it known that I, ENooH A. SWANSON, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska,have invented new and useful Improvements in Pumps, of which the following is a specification.

My present invention has reference to an attachment for automobiles or similar motor driven vehicles.

My object is to produce a means which may be readil attached to or removed from the running oard of an automobile and which includes a rotary pump that is operated by one of the drive wheels of the machine, when the said wheel has been jacked up to bring the same above the ground surface and the engine is permitted to run, said pump designed to have its inlet connected with a source of water supply and its outlet provided with a hose whereby water will be pumped for washing the auto mobile, for watering vegetation, extinguishing fires or for any other desired purpose.

The foregoing, and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative association of parts, such as is disclosed by the drawings which accompany and which form part of this specification.

In the drawings Figure 1 is a view illustrating the application of the improvement.

Figure 2 is a sectional view on the line 22 of Figure 1.

Figure 3 is a sectional view on the line 3-3 of Figure 2.

The remaining figure illustrates details.

Referrin now to the drawings in detail the numera 1 designates the rear portion of any ordinary construction of automobiles, 2 the running board of the machine, and 3 one of the drive wheels of the machine.

0n the under face of the running board 2, adjacent to the fender for the wheel 3, T bolt or otherwise secure spaced brackets 4-4 respectively. Each of these brackets has an angle end which is provided with a round opening for the reception of a shaft 5. The shaft is removably associated with the brackets so that when my improvement is not in use the same can be detached from the machine. One end of the shaft projects a suitable distance outwardly from the running board 2, and this projecting end re- Serial No. 524,412

ceives thereon a socket or eye 6 provided on an arm 7 depending from a hub 8 on the casting for the body portion 9 of a rotary pump 10. The shaft 11 for the pump blades finds a bearing in the hub 8 and projects therebeyond, having secured to its projecting end a roller 12. Preferably the roller 12 has a corrugated periphery as indicated by the numeral 13, and if desired, the roller may be provided with a compressible ring whose outer surface is corrugated. The roller 12 is formed in contacting engagement with the drive wheel 3 of the automobile, in a manner which will presently be apparent.

In the pump casing there is a rotor of a peculiar construction, the same including a flat peripherally rounded body 14 to which the shaft 11 is centrally secured, the said body having a central passage therethrough for the reception of opposed blades 15 and 16 respectively, while between the blades, at the inner ends thereofthere is a pressure spring 17. The spring forces the blades in contact with the inner rounded wall of the pump casing. The pump casing is provided with an inlet passage surrounded by an outwardly extending nipple 18 and an outlet passage which is also surrounded by an outwardly extending nipple 19. For distinction, the outer plate of the pump casing is indicated by the numeral 20, the same bein bolted thereto in the usual manner.

ournaled on the shaft 5, outward of the arm 7 there is the angle end 20 of a lever 21. The angle portion 20 of the lever is given ahalf twist upon its adjacent to its outer end, and its said outer end has a threaded opening, the threads of which being engaged by the shank of a wing bolt 21. The bolt contacts with the outer side of the pump casing.

It should have been stated that the eye 6 on the arm 7 of the pump casing has a binding engagement with the shaft 5 through the medium of a bolt member 22 so that the pump is prevented from movement in an outward direction on the shaft, the inward movement being prevented by the contact of the eye 6 with one of the brackets 4, and also for distinction the means for holding the shaft against longitudinal movement through its bearings in the brackets 4 are indicated in the drawings by the numeral 23.

The outer end of the lever 21 has an opening therethrough for the reception of one coil or convolution of a spring 24, the op posite end of the spring having an extension which terminates in a hook-like portion 25, and this hook engages under the outer edge of the running board 2 of the machine 1; It will be apparent that the spring influenced lever 21, by virtue of the contacting engagement of the wing bolt 21', carried thereby will swing the pump casing to cause the roller 12 to frictionally engage with the tire on the drive. wheel 3 of the automobile. This pressure is regulated-by adjusting the bolt 21. The rear of the machine is jacked up so that the drive Wheels are arranged ofi of the ground surface. The engine is permitted to run to turn the ground wheels and such turning of the wheels will obviously turn the roller 13 which being keyed to the shaft 11 of the rotor 14 will cause the-same to turn in the pump casing. Of course, a conductor in the nature of a tube 26 is screwed in the inlet nipple 18, and a flexible hose 27 has one end screwed in the outlet nipple 19, and whereby water drawn through the tube 26 by the rotary pump will be forcibly ejected through the hose 27. The forcibly ejected water may be used for cleaning the machine, for watering vegetation, for directing the same into cisterns in dwellings, for extinguishing fires or for any other desired purpose.

Having described the claim 1. A pump including a horizontally arranged supporting element disposed in close invention, I

proximity to the drive element, an arm" xed to the supporting element, a pump casing carried by the arm and having spaced projections extending transversely across its periphery, a rotor in the pump, a drive ele-- ment carried thereby and arranged exteriorly of the casing and adapted to be engaged by the drive element, an arm pivoted to the first mentioned arm, and provided with a set screw adapted to engage any one of the projections to hold the casing against movement and to hold the drive element against the driving element, and resilient means connected with the arm and connected with the stationary object to urge the casing toward the driving element.

2. A pump comprising a bracket adapted to be mounted upon the underface of an automobile in proximity to one of its drive Wheels, a shaft journaled in the bracket, an arm fixed to the shaft,'a pump casing carried by the arm, a pump element in the easing, a driven element arranged exteriorly of the casing and fixed to rotate with the pump element and adapted toengage one of the drive wheels of an automobile, a series of transversely extending abutments on the pump casing, an L-shaped lever pivoted to the arm, a set screw carried by one end of the lever, and engageable with any one of the abutments whereby to hold the casingagainst movement in one direction, and a contractile spring connected with the arm and part of the automobile whereby to normally urge the casing toward the drive wheel.

In testimony whereof I afiix my signature.

ENOOH A. SWANSON.
